Threshold — , , Exile two cards from your graveyard: Target player discards a card. Activate only as a sorcery and only if seven or more cards are in your graveyard.

First strike, vigilance

Protection from Vampires, from Werewolves, and from Zombies

You may reveal the first card you draw each turn as you draw it. Whenever you reveal an instant or sorcery card this way, create Cherubael, a legendary 4/4 black Demon creature token with flying.

Whenever Inquisitor Eisenhorn deals combat damage to a player, investigate that many times. (Create a Clue token. It's an artifact with ", Sacrifice this artifact: Draw a card.")

Vigilance

Unquestionable Wisdom — Other creatures you control get +1/+0 and have vigilance.

Hunt for Heresy — , : Tap target creature an opponent controls. Investigate. (Create a Clue token. It's an artifact with ", Sacrifice this artifact: Draw a card.")

If equipped creature would deal combat damage, it deals double that damage instead.

If another creature would deal combat damage to equipped creature, it deals double that damage to equipped creature instead.

Equip

Prevent all damage target attacking or blocking creature would deal this turn. If that creature is black or red, destroy it.

Militant Inquisitor gets +1/+0 for each Equipment you control.

When Norn's Inquisitor enters, incubate 2. (Create an Incubator token with two +1/+1 counters on it and ": Transform this artifact." It transforms into a 0/0 Phyrexian artifact creature.)

Whenever a permanent you control transforms into a Phyrexian, put a +1/+1 counter on it.

Tap five untapped Wizards you control: Search target player's library for up to five cards and exile them. Then that player shuffles.

+1: Up to two other target planeswalkers you control phase out at the beginning of the next end step. (Treat them and anything attached to them as though they don't exist until your next turn.)

−2: For each opponent, return up to one target nonland permanent that player controls to its owner's hand.

−7: Target artifact you control becomes a 9/9 Construct artifact creature and gains vigilance, indestructible, and "This creature can't be blocked."
